All Questions (10)
A) To introduce a new, unrelated idea to the essay.
B) To summarize the entire essay's argument.
C) To state the paragraph's single, controlling idea.
D) To provide a concluding thought for the previous paragraph.
Correct Answer: C
Based on the principles of paragraph focus (Essential Knowledge 1), a paragraph develops a single, controlling idea. The topic sentence's main function is to express this controlling idea, thereby establishing the focus for that specific paragraph.
A) To increase the paragraph's word count and complexity.
B) To introduce advanced vocabulary and tone.
C) To create a smooth logical flow and connect ideas between sentences.
D) To ensure every sentence has a different grammatical structure.
Correct Answer: C
Essential Knowledge 2 states that cohesion is achieved through devices like pronoun references and repetition. The purpose of these devices is to create a smooth flow and establish clear connections between sentences, making the paragraph easier for the reader to follow.
A) The high initial investment for wind turbines and solar panels is a significant barrier for many developing nations.
B) Furthermore, the intermittent nature of solar and wind power requires expensive energy storage solutions.
C) The aesthetic beauty of a field of sunflowers, a potential source for biofuels, is undeniable.
D) Government subsidies, while helpful, often fail to cover the long-term maintenance costs of these technologies.
Correct Answer: C
Essential Knowledge 1 requires a paragraph to maintain focus on a single, controlling idea. The paragraph's focus is on economic challenges. Sentences A, B, and D all relate to this economic focus. Sentence C shifts the topic to aesthetics, which is unrelated to the economic argument and thus disrupts the paragraph's unity.
A) To confirm that the new paragraph will repeat the exact same idea as the previous one.
B) To signal a shift in the argument, introducing an opposing or different perspective.
C) To provide a detailed example supporting the previous paragraph's main point.
D) To conclude the essay's overall argument with a final thought.
Correct Answer: B
Essential Knowledge 3 explains that transitions signal relationships between ideas. Phrases like "On the other hand" or "In contrast" specifically signal a relationship of contrast, alerting the reader that the new paragraph will present an opposing viewpoint or a different aspect of the topic discussed in the previous paragraph.
A) Parallel structure
B) Use of a synonym
C) Direct repetition of a key word
D) Cause-and-effect transition
Correct Answer: B
Essential Knowledge 2 lists the use of synonyms as a key cohesive device. In this example, the word "rules" in the second sentence serves as a synonym for "regulations" in the first sentence. This creates a clear and logical connection between the two ideas without being unnecessarily repetitive.
A) Similarly,
B) For example,
C) Consequently,
D) However,
Correct Answer: D
According to Essential Knowledge 3, transitions signal the relationship between ideas. Since the second paragraph will present a contrasting idea (drawbacks vs. benefits), a transition word that indicates contrast, such as "However," is the most appropriate choice to guide the reader.
A) Adding more complex vocabulary to make the sentences sound more academic.
B) Combining all the sentences into one long, complex sentence to force a connection.
C) Deleting the sentences about the queen bee, beekeeping history, and honey, keeping only details that directly support the topic of pollination.
D) Moving the topic sentence to the end of the paragraph to act as a conclusion.
Correct Answer: C
This question addresses both focus (Essential Knowledge 1) and cohesion (Essential Knowledge 2). The paragraph lacks focus because it includes sentences that do not support the controlling idea. The best way to improve both focus and cohesion is to remove the irrelevant information, ensuring all remaining sentences directly develop the main point stated in the topic sentence.
A) repetition of key terms
B) use of pronouns to refer to antecedents
C) introduction of a completely new controlling idea
D) use of parallel grammatical structures
Correct Answer: C
Based on Essential Knowledge 2, cohesive devices like repetition, pronoun reference, and parallel structure are used to link sentences and ideas logically. According to Essential Knowledge 1, introducing a completely new controlling idea would disrupt, rather than enhance, a paragraph's cohesion and focus.
A) The other sentences should introduce counterarguments to challenge the topic sentence.
B) The other sentences provide evidence, explanation, or examples to support the claim made in the topic sentence.
C) The topic sentence serves as a brief summary of the sentences that come before it in the essay.
D) Each sentence should explore a different aspect of the essay's thesis, independent of the topic sentence.
Correct Answer: B
Essential Knowledge 1 states that a paragraph is a unified group of sentences developing a single, controlling idea, which is often in the topic sentence. Therefore, all other sentences in a focused paragraph must directly support, elaborate on, or prove the idea presented in that topic sentence.
A) In addition to fostering community, social media is also used for marketing and news dissemination.
B) While the potential for connection is significant, this digital landscape is not without its perils; in fact, the very structure that creates community can also breed isolation.
C) To understand social media, one must look at the history of the internet and early online forums.
D) For instance, many users find friends through online gaming communities, which proves that social media is beneficial.
Correct Answer: B
This question requires a sophisticated understanding of transitions (Essential Knowledge 3). An effective transition must both acknowledge the previous point (community) and introduce the new, contrasting point (isolation). Option B does this perfectly by using the concessional clause "While the potential for connection is significant..." to link to the first paragraph and then pivoting to the new argument about isolation. The other options either change the subject (A, C) or only support the previous paragraph's point (D).
